INVENTOR- LEO G. PECK ATTORN EY United States Patent PUMP ADAPTER FORLIQUID CONTAINERS Leo G. Peck, Ladue, Mo., assignor to Pecks ProductsCompany, St. Louis, Mo., a corporation of Missouri Application October28, 1955, Serial No. 543,396

4 Claims. (Cl. 222-382) This invention relates in particular to acertain new and useful invention in devices for mounting a pump upon aliquid container to facilitate measured dispensing of its contents.

Heretofore, the transfer of liquids from drums or metal barrels hasposed a problem in many industries. In such fields as cosmetics, soapsand detergents, insecticides and numerous others, the user will in manyinstances merely repackage the drum contents in small containers forindividual use. In view of the unwieldy weight and size of such drums,which, when full, may weigh several hundreds of pounds, the directtransfer of liquid therefrom to such individual containers has not beenadequately solved. customarily, the drum contents have been dischargedeither by means of a directly attached faucet or tilting of the drum toan intermediate receptacle, which can be conveniently handled and is, inturn, emptied into a dispensing unit forming a part of an assembly orfilling line. Efiorts have also been made to connect the drum by asuitable pipe to a remotely located assembly-line dispenser, with a pumpbeing connected in the line to effect fluid flow.

None of the expedients above mentioned have provided the efiiciency andeconomy, both in material and labor, necessary in low cost production.

Therefore, it is an object of the present invention to provide a unit tobe mounted upon large quantity liquid containers which will accommodatea pump for dispensing measured amounts whereby the container contentsmay be transferred directly to an ultimate receptacle.

It is another object of the present invention to provide a unit formounting pumps lJJPOIl liquid containers, as drums, which will adapt thedrum for immediate incorporation in an assembly or filling line.

A further object of the present invention is to provide a unit of thetype stated which may be economically manufactured, which is reliableand durable in use, and which is easily and elfeetively utilized.

These and other detailed objects are obtained by the structuresillustrated in the accompanying drawing, in which- Figure 1 is a sideview, partially cut away, of a drum, being connected to a pump by anadapter mounted thereon; said adapter being constructed in accordancewith and embodying the present invention.

Figure 2 is a perspective view of the adapter.

Referring now by reference characters to the drawing, A designates ametal drum or barrel, such as is commonly utilized in industry fortransporting liquid material, as oil, gasoline, liquid chemicals, andsimilar products. Drum A does not form a part of the invention, but isshown as exemplary of industrial drums with which a pump adapter B maybe used. Said drum A comprises a cylindrical side wall 1 withreinforcing ridges 2, a bottom wall 3, and a head or top wall 4 having athreaded opening or more commonly called bung 5, within which isnormally engaged a threaded closure plug (not shown). Provided forengagement within bung 5 is a pump adapter B, which may be cast of anysuitable metal or fabricated 2,818,201 Patented Dec. 31, 1957 ICC fromthermosetting plastic or other non-metallic materials for producing arigid structure. Adapter B comprises an elongated tubular body or casing6, the normally upper end of which is externally threaded, as at 7. Atits other, or normally lower, end tubular body 6 is diametrallyincreased to form a relatively short base 8 which is externallythreaded, as at 9, for engagement with the threading of bung 5 formounting adapter B securely upon drum A with the tubular body 6extending upwardly from top wall or drum head 4.

The upper threaded end 7 of adapter B is of appropriate outside diameterfor accommodating an internally threaded cap or fitting 10 of awell-known type of measured-quantity dispensing pump C, made preferablyof plastic, which includes .a dispensing spout 11, a piston having afinger grip 12 formed at its upper end, a chamber 13 of predeterminedvolume with the lower end thereof in communication with a rigid pipe ortube 14 of such length as to project downwardly below the lower end ofadapter B and top wall 4 of drum A when pump C is mounted on adapter B.Attached to the end of pipe 14 is a length of flexible tubing or hose 15which extends to the bottom of drum A to assure withdrawal of all liquidtherefrom.

In actual practice, by use of the present invention, drum A may besituated at any convenient point such as within an assembly line wheresmall individual containers are either being filled with the liquid inthe drum or being supplied predetermined quantities thereof for mixturewith other ingredients. The closure plug is removed from drum A and pumpadapter B is secured at position with base threads 9 engaging thethreads of the bung hole 5. Drum A is thereby adapted for connection topump C, the latter having its chamber 13 and rigid tube 14 receivedWithin tubular body 6 of adapter B, and cap or fitting 10 is threadinglysecured to neck '7 to fix pump C upon adapter B. Flexible tubing 15,which will have been passed through tubular body 6 upon mounting of pumpC, will extend to the bottom of drum A so that the entire contentsthereof may be pumped without the necessity of tilting of said drum A.Finger grip 12 of pump piston will thus be presented at a convenientelevation for operation whereby an operator need only place a small,ultimate container to be filled at spout 11 and by operation of pump C apre-measured quantity of the liquid contents of drum A will bedischarged thereinto.

Thus, by the use of pump adapter B the heretofore considered unwieldycharacter of drum A is effectively overcome, since the same may be usedin immediate conjunction with filling operations, thereby obviating theneed of any intermediate receptacles for transferring the drum contentsto the ultimate container. Pump adapter B may be of any desired lengthso that the finger grip of pump C will be at a comfortable height toconduce to minimum fatigue of the operator. Additionally, it should benoted that pump adapter B may be sized for use with any industrial drumand hence has wide applicability in industry. Furthermore, its usage hasproved highly economical from a labor standpoint as well as assuring theavoidance of inadvertent loss of the drum contents. It my bemanufactured most cheaply of highly durable material.

It should be recognized that, if necessary for engagement purposes, thethreads at neck 7 and base 9 may be provided on the inner surface orbore wall of tubular body 6 instead of outwardly as shown in thedrawing.

It should be understood that changes and modifications in the formation,construction, arrangement, and combination of the several parts of thePump Adapter for Liquid Containers may be made and substituted for theseherein shown and described without departing from the nature andprinciple of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:
